IMPROVEMENT IN MITRE PLANES.

SPECIFICATION.

invented a newiand useful Improvement in Plane; and I do hereby declarethat. the following is a full, clear, and exact descriptionv thereof,which will enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspecication, in which- Y Figure 1 is a top view ofvmy improved plane andguide-plate, partrbeing broken away to sh'ow the construction. i

Figure 2 is an end view of the same.

Similar letters of reference indicate like parts. i

My invention has for its object to furnish an improved apparatus bymeans of which the ends of mouldings may be cut at any desired bevel soas to make a 4close joint; and it consists, first, in the plane,constructed and arranged as hereinafter more fully described; and,second, in the adjustable guide-plate, iu combination with the plane,said guide-plate being constructed and arranged as hereinaftermore'fully described. i

A is the plane, which is furnished with two plane-irons, al and a2,placed, one in each end of the plane and inclined in oppositedirections, as shown in fig. 1. The cutting edges of these plane-irons,al and a, project at the side of the plane, instead bf. projecting atthebottom, in the usual manner. The plne-irons al and a2 are set ingrooves in the body of the plane, and are secured in place by woodenwedges, a:s and a4, in the ordinary way, a space being formed in frontof said irons andnwedges for the escape of the shavings. The handle, a5,Vis attached to the central part of the upper side, as shown in g. 1,and should be of such a form that the plane may be conveniently workedin either direction. B is the guide-plate, in connection withwhich theplane is used. The face of the plate B is grooved longitudinally nearone edge, with a shallow groove of such a size that the lower face orside of the plane, A, may accurately it into it, as shown in iig. 2, soVthat it may move in a direct line when operated. `The depth of thisgroove should be such that the upper surface of the plate B may be in aline with the lower corner of the plane-irons, as shown in iig. 2. C arethe guide-bars, against which the mouldings are held while beingoperated upon. These guide-bars, C, are pivoted at their inner ends tothe plate B, and they are clamped at any angle to give any desired bevelto the ends ofthe moulding by the A screws D and thumb-nuts E. Thescrews D pass through slots formed in the plate B, their heads fittinginto a channel formed on the under side of said plate.

I claim as new, and desire to secure by Letters Patentl The grooved andslotted plate B and pivoted guide-barsC, when used in combination withthe plane A,

having its iron, al a2, inclined in opposite directions, substantiallyas described for the purpose specified.

JOHN SAWYER.
